Each culture has its own halvah, united only by nameâwhich derives from the Arabic word for âsweetââand the fact that each is a sweetened candy or dessert, often an ancient and beloved recipe. A trip to Israel is not complete without sampling the countryâs halvah.
The amount of vitamin D you get from exposing your bare skin to the sun depends on: 1  The time of day â your skin produces more vitamin D if you expose it during the middle of the day. 2  Where you live â the closer to the equator you live, the easier it is for you to produce vitamin D from sunlight all year round.
Vitamin D deficiency can lead to osteoporosis in adults or rickets in children. Food Sources The body makes vitamin D when the skin is directly exposed to the sun. That is why it is often called the sunshine vitamin. Most people meet at least some of their vitamin D needs this way. Very few foods naturally contain vitamin D. As a result, many foods are fortified with vitamin D. Fortified means that vitamins have been added to the food. Fatty fish (such as tuna, salmon, and mackerel) are among the best sources of vitamin D.
